Key Features of Honeywell cc tdor01

• 32 Independent Relay Channels: This feature gives you 32 digital output relay channels that let you control field equipment like solenoids, valves, and indicators with great accuracy.
• High Reliability Relay Outputs: Each channel can handle 0.5A at 24VDC and has mechanical relay contacts for strong switching in tough situations.
• Electronic Short-Circuit Protection: Built-in safety features keep the system running by stopping damage from wiring problems and overloads.
• Non-Redundant Coated IOTA Design: Epoxy-coated to further protect against dust, moisture, and corrosive environments in maritime and industrial settings.
• Wide Operating Temperature Range: Works well in harsh circumstances from -40°C to 85°C.
• Flexible Channel Configuration: Lets you turn channels on and off individually and get diagnostic feedback for better control.
• Easy to install: Just plug it in and attach it on Honeywell Series C I/O racks. It works with C300 controllers.
• High Noise Resistance: Electromagnetic compatibility fulfills industrial requirements, which cuts down on false triggers.
• Low Power Consumption: Efficient 24VDC operation lowers energy expenses for big DCS systems.
• Comprehensive Diagnostics: Experion PKS can find faults and report on their state on board, allowing for proactive maintenance.

Frequently Asked Questions

What is the difference between CC-TDOR01 and CC-TDOR11?

The CC-TDOR01 is a non-redundant, 6-inch Series C digital output relay IOTA assembly designed for standard single IOM configurations. The CC-TDOR11 is a redundant, 12-inch IOTA assembly built to support dual redundant CC-PDOB01 output modules on a single field termination block.

Can the CC-TDOR01 switch both AC and DC voltages on adjacent channels?

Yes. Each channel provides independent galvanic isolation rated up to 1500 VAC RMS. You can switch 230 VAC lighting or contactor circuits on one group of channels while switching 24 VDC instrument solenoids on adjacent channels, provided you follow separation rules for field wiring bundles.

What is the maximum wire gauge accepted by the CC-TDOR01 screw terminals?

The removable terminal blocks accommodate standard single-core or stranded wire sizes ranging from 0.2 mm² to 2.5 mm² (24 AWG to 12 AWG). We recommend using insulated bootlace ferrules when landing stranded marine-grade conductors.

How does the conformal coating benefit marine and offshore installations?

The conformal coating on the 51308376-175 PWA meets ISA-S71.04 Class G3 environmental specifications. It prevents dendritic copper growth, dielectric breakdown, and short-circuiting caused by condensation, chemical sulfur gases, and sea-salt aerosol ingress.
